How to connect to Linux server by SSH?
To connect to a Linux server using SSH, follow these steps:
1. Obtain the SSH command: Open your terminal application (such as the Terminal on macOS or Linux, or PuTTY on Windows) and ensure that SSH is installed. If not, install it using the package manager on your respective operating system.
2. Get the server’s IP address: Obtain the IP address or hostname of the Linux server you want to connect to. This information is typically provided by the server administrator or hosting provider.
3. Open a terminal: Launch your terminal application and enter the following command, replacing "username" with your username and "server_ip" with the IP address or hostname of the Linux server:
ssh username@server_ip
For example:
ssh john@192.168.0.1
4. Enter your password: When prompted, enter your password associated with the provided username. Note that while typing the password, no characters are displayed for security purposes. Press Enter after typing the password.
5. Verify the connection: If the login credentials are correct, you should now be connected to the Linux server via SSH. You’ll see a welcome message or the default shell prompt indicating a successful connection.
It’s worth mentioning that SSH keys can be used for authentication instead of passwords for added security. This involves generating a key pair on your local machine and adding the public key to the Linux server. However, the steps for key-based authentication go beyond the scope of this explanation.
Remember to check the documentation specific to your operating system, as some distributions may have slight variations or require additional steps when connecting to Linux servers using SSH.
